absolutely not........
Ever so briefly, just don't be focussed on the shoulder, the answer and the best treatment lies in the cervical spine. Not manipulation, not massage, but mobilisation with a view to restoring a non protected state of normal freedom of movement , specifically, though not limited to , C456, ipsil. Continuous Mobilisation applied there to facet joints will restore this non protected state, leading progressively to a less irritated series of nerve roots , associated with normal sensations ( or lack therof ) to the shoulder complex..
